Description
This Audi ILM passenger-side power supply module fits Audi A8 D3 4E models and carries primary OEM number 4E0907280 with Bosch reference F005S00099. It is an original electrical control unit used within the vehicle’s onboard power distribution system and is designed for the passenger-side ILM position.
Its job is to manage and distribute electrical power to selected onboard systems, helping maintain stable voltage supply and coordinated operation of connected circuits. In a luxury platform with multiple comfort and body electronics, this module supports reliable communication and controlled power delivery within the wider vehicle electrical network.
Common signs of a faulty unit include intermittent electrical malfunctions, unexpected loss of power to related vehicle functions, warning messages, battery drain concerns, or irregular operation of comfort and body electrical systems. Because these symptoms can overlap with wiring or battery issues, accurate diagnosis is always recommended before replacement.
This is a used original part, removed from a vehicle and tested. Match the exact OEM number before ordering. Professional installation is recommended, and coding, programming or adaptation may be required depending on the vehicle’s equipment and control unit configuration.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
